摘　　要：为进一步研究化肥氮素在农田中的利用率及增产效应机理。本文主要综述了农田系统中单施化肥、秸秆配施化肥、有机肥配施化肥及绿肥配施化肥处理中化肥氮素去向,为今后提高农田系统中的氮肥利用率及农田生态的可持续发展提供参考。In order to further study the utilization rate of chemical fertilizer nitrogen in farmland and the mechanism of yield increase effect.In this paper,we mainly reviewed the nitrogen fate of chemical fertilizers in single application of chemical fertilizers,straw with chemical fertilizers,organic fertilizers with chemical fertilizers and green manure with chemical fertilizers treatments in the farmland system,which will provide reference for the future improvement of nitrogen fertilizer utilization rate in the farmland system and the sustainable development of farmland ecology.
